Justin Timberlake can liven up any party, even a stranger's wedding!

The "Can't Stop the Feeling!" singer helped one random couple make their special day even more memorable when he dropped in on a wedding ceremony at the Mount Washington Hotel in New Hampshire on Saturday.

Chelsey Gaudet and Ryan Parks were snapping photos before the reception when Timberlake showed up, seemingly out of the blue, to snap a photo with the happy couple.

Gaudet explained to ET that the pop star was in New Hampshire that day, eating lunch near her wedding venue and, unbeknownst to her, the father of the bride saw Timberlake and asked him for a favor.

"So we were taking the first look photo and all of a sudden Justin Timberlake appears out of nowhere, shakes my husband's hand and congratulates us and takes a photo," Gaudet marveled. "We thought it was awesome of him to do that, but had no idea it would go viral."
